I bought a set of very nice LED nav lights not too long ago. Last I had them turned on and as I walked around I noticed they were visible from abaft the beam. I was under the impression that the light from port and starboard lights should only be visible from forward of the beam. I think at night it could cause a good deal of confusion when viewed from another boat.

Should be visible 22.5 degrees abaft of the beam, in an ideal world, the cut off of the stern light should match with that of the side light.

That's two points in a yet more ideal world.

I was going to buy some but they want some real money for them.
Kind of wish I did now, The anchor light did not survive the stepping.
Its below the spreaders but I still have to find a skinny guy to take a ride up the mast.:D

If it's below your spreaders, it's probably not your anchor lite. Anchor lite should be at the masthead. The lite below your spreaders is probably your steaming lite.

I was taught to display the anchor light significantly lower than the masthead (Usually in the foretriangle) because otherwise it could easily be mistaken for a star...

Rule 30


Anchored Vessels and Vessels Aground

(a) A vessel at anchor shall exhibit where it can best be seen:

(i) in the fore part, an all-round white light or one ball;
(ii) at or near the stern and at a lower level than the light prescribed in subparagraph (i), an all-round white light.
(b) A vessel of less than 50 meters in length may exhibit an all-round white light where it can best be seen instead of the lights prescribed in paragraph (a) of this Rule.
(c) A vessel at anchor may, and a vessel of 100 meters and more in length shall, also use the available working or equivalent lights to illuminate her decks.
(d) A vessel aground shall exhibit the lights prescribed in paragraph (a) or (b) of this Rule and in addition, where they can best be seen;

The key here is that the anchor light is an all-round light. It can be in the fore triangle, run partway up the forestay or backstay, or more commonly at the masthead. A light on the spar at the spreaders will not be very visible from astern. This light is probably visible from forward to 2 points aft of the beam--steaming light.

Mine is forward below the spreaders with the stern light covering the rear.

That would be your steaming light.
Stern light only when sailing, stern light and steaming light when under power.

I had no provisions on the mast for a anchor light beyond what I described. Over on the bristol forum they said that was the setup.
Help a powerboat guy out please as I am getting bad info.
I am about to hang a kero lamp from a halyard:rolleyes:

That would work. Use a bridle attached to the backstay and hoist it with the main halyard, this will keep it away from the mast.
There are also some 12 volt lights available with long cords that can be hoisted up the same way.

Hamilton Marine...
Item #: DAV-3300
Uses only .074 amps per hour! Thats under one amp-hour a day! This new anchor/cockpit/utility light is visible for three nautical miles. It pays for itself in reduced charging cost. Available in plug-in or hard wired models.

Working riverine towboats are going to all LED now. They last a really long time, they're tough, and we can get about four night's use out of the portable barge lights, as opposed to maybe a night and a half out of the batteries prior to.

White is still hard to get in the sort of intensity( relative to cost) you need for a stern light though. I just switched my bow lights to led though.
I ran one of those davis anchor lights for oooo 15 years, still carry it as backup.

Check these folks out, if nothing else they might give the handy person some ideas about a DIY solution.

I got a set of Aquasignal S-32 LED lights (port, stbd, stern). These are Coast Guard rated and were reasonable cost. I'm quite happy with them.
